Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
With reference to accompanying drawing.
Real-time monitoring device of the present utility model comprise simulating pile works cylinder 1, for the test soil layer 2 in Simulated Water base ring border and test water layer 3, cylinder 1 the transparent and sealed bottom of perisporium, the bottom of cylinder 1 is embedded in test soil layer 2, in order to ensure the stability that cylinder 1 is imbedded, cylinder 1 height be embedded in test soil layer 2 is not less than 2 times of cylinder external diameter, the upper end of cylinder 1 stretches out in test water layer 1, anti-sealing enters cylinder inside, guarantee that cylinder 1 inside is not subject to the impact of water, guarantee test effect.
Real-time monitoring device also comprises camera 4, camera 4 is placed in the inner space of cylinder 1 by support 5, the effect of camera 4 is the collections carrying out scoured pit's depth and change width situation, the camera lens of camera 4 vertically down, minute surface is horizontal, and, align with cylinder bottom center in the vertical direction in the optical center of camera 4, guarantee that collection point hits exactly, collection position is evenhanded, camera 4 connects external processing unit by data wire, external processing unit can be PC, pass through PC, the photo collected is carried out collecting and processing, photo disposal can adopt conventional image processing tool, guarantee that the angle of often opening photo is all the same, to carry out the analysis of result.
In order to the impact avoiding the refraction of water to bring to collected by camera as far as possible, the horizontal level of camera 2 should lower than the horizontal plane of test water layer 1.
Transparent cylinder 1 is organic glass bucket, in order to ensure the intensity of cylinder 1, actual environment is washed away in simulation better, the bucket wall of organic glass bucket should have certain thickness, but then, in order to ensure the accuracy of collected by camera, organic glass bucket should not be too thick, otherwise the refraction of glass can produce considerable influence to the shooting of camera, therefore the bucket wall thickness of organic glass bucket should be arranged between 1.5-3mm, is preferably 2mm, simultaneously, the material of organic glass has certain screen resilience, stressed similar with seabed cylindrical works.The bottom thickness of organic glass bucket is 2-5mm, and be preferably 3mm, bottom should not be too thick, on the basis of guaranteeing its intensity, should get over Bao Yuehao bottom it, in order to avoid produce too much refraction, affects the shooting effect of camera.
The external surface of organic glass bucket is provided with graduation mark, before the test, needs to carry out basis according to graduation mark to scoured pit's depth and width and demarcates, after test, on the picture gathered, come to calculate accordingly according to graduation mark.
The support 5 of camera 4 is connected with telescopic mounting, camera can be mobile in cylinder 1 inside under the driving of telescopic mounting, thus the position of adjustment residing for camera 4, to choose best shooting angle, as collection position, telescopic mounting can adopt the forms such as screw rod.
